I just spent some more time A, B ing the drums...most of the drums [kits and accessory sounds are identical] with some pitch and filter changes..
The G70 sounds more to my liking for the most part...I do like both instruments' drum sets..

The G70 is richer on the cymbals..more harmonics and decay differences than on the E-60..A more natural feel to me..I am sure that most of the drum kits can be edited on the G70 to match the E-60..if someone wanted the E sound...

I don't see either instrument drums as "far better"..unless we are comparing drums of another brand..
